Name:  Automatic kjeldahl nitrogen analyzer

Model:  KDN-04C/KDN-08C/KDN-20C

Note:     digestive furnace is not included in standard configuration

 

Characteristics:

1. Adopt microcomputer controlling process

2. Automatically control distills, add water, control water level and cut off water supply

3. Various security protections: digestive system security device, steam generator water shortage alarm, water level detection fault alarm

4. Instrument shell adopts specially made plastic spray steel; working area adopts ABS anticorrosive board. Avoid chemical reagent corrosion and mechanical surface damage, acid proof and alkali proof.

5. Once detected fault, controlling system will power off automatically

6. Adopt tap water source, wide adaptability, and requirement for test is low.
